Research on Red Light Therapy has been ongoing since 2000 - and surprise, surprise - it is a non-invasive solution to dealing with menstrual pain in an effective manner. 

The penetration of the light onto the skin increases blood circulation as well as uterus elasticity, which relieves women of mild and severe menstrual pain, while also improving fertility. 

But that's not all! Using near and far-infrared light, RLT not only improves skin’s appearance, but also reduces wrinkles, scars, redness and acne, while also being known to treat bone fractures and arthritis. 

How effective is RLT for menstrual cramps? 

Infrared light is phenomenal for pain relief. As it penetrates into the body, the light acts directly on irritated nerve endings providing rapid relief and tension reduction. It deeply penetrates the skin, increasing blood flow, and thus reducing period cramps. 

Science assessing the effects of infrared light on menstrual pain dates back to no longer than a decade ago. Not only did scientists find that infrared light is good for period pain, but it’s also good for injuries and arthritis. It is a great revolution for non-pharmacological remedies for common health conditions. 

Infrared light is a non-invasive treatment that has the ability to penetrate your skin, reaching deep down into your cells and tissue. The low-level heat from the light triggers microcirculation and reduces inflammation, reducing period pain. Fun fact? The light also encourages collagen production, which is great for uterus health.

How did interest in red light therapy evolve?

NASA originally began experimenting with red light therapy on plant growth in space and then to help heal wounds in astronauts. Like many developments, other potential uses began to be investigated.

In fact, red light therapy is already widely medically accepted in its use in photodynamic therapy. In this therapy, low-power red laser light is used to activate a photosensitizer drug. The interaction creates a chemical reaction that destroys cells. It’s used to treat some skin conditions, including skin cancer and psoriasis, acne and warts and other types of cancer.
